AIR-VENT FOR BARRELS.

Specification of Letters Patent.

Fatented Jan. 18, 1916.

Application filed October 13, 1914. Serial No. 866,482.

To all whom it may concern:

Be it known that I, CLARENCE N. EASTER, a citizen of the United States, residing at West Chester, in the county of Washington, State of Iowa, have invented certain new and useful Improvements in Air-Vents for Barrels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the'art to which it appertains to make and use the same. 8

This invention relates to barrels, casks, kegs and the like, and has particular reference to air vents, the object of the present invention being the provision of a simple and novel device adapted for attachment upon barrels, though particularly steel oil barrels, whereby air may be admitted or let out according to circumstances.

An important object is the provision of a device of this character adapted for use and which will efliciently operate when in a ver tical or horizontal position, means being provided whereby air may be admitted regardless of the position of the barrel.

Another object is the provision of a device of this character which will be extremely simple and inexpensive, easily applied and a general improvement of the art.

lVith these objects and advantages in view, the invention consists in the novel construction and arrangement of parts to be hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which- Figure 1 is a vertical sectional view through my device applied to a fragment of a barrel and showing it in its closed position, Fig. 2 is a sectional view through my device extending horizontally from a fragment of a barrel and in its entirely open position, and Fig. 3 is a similar view of my device upon a fragment of a barrel and extending vertically therefrom, the device being open.

Referring more particularly to the drawing, the numeral 5 designates a fragment of a barrel to which my device is applied.

My device comprises an internally screw threaded sleeve 6 disposed within an opening in the barrel and provided with a flange 7 bolted or screwed upon the side of the barrel. The movable portion of my device comprises a screw threaded member 8 engaging within said threaded sleeve and provided with a head 9 of a shape suitable for engagement with a wrench. A gasket 10 is disposed between the head 9 and the sleeve 6 whereby the device will be airtight when the screw threaded member is screwed down tightly. The lower end of the screw threaded member 8 is reduced in thickness as shown at 11 so that the portion 11 will be of considerably less diameter than the interior of the sleeve 6. The portion 11 terminates in a reduced portion 12, forming a shoulder 13 against which abuts a washer 14 disposed upon the reduced portion 12 and prevented from withdrawaltherefrom by a cotter pin 15. The parts of the device being in the position shown in Fig. 1, that is, the screw threaded member 8 being screwed as far as possible into the sleeve 6, the device will be airtight.

The barrel being in a position such that my device will be disposed in a horizontal position as shown in Fig. 2, in order to provide an air vent, it is merely necessary to unscrew the member 8 out of the sleeve 6, whereupon the reduced portion 11 will be disposed within the sleeve 6. In view of the fact that the reduced portion 11 is of considerably less diameter than the sleeve 6, ample space will be provided between the portion 11 and the sleeve for the passage of air. The provision of the washer l4 and cotter pin 15 prevents the screw threaded member 8 from being pulled entirely out and lost.

Then the barrel is in such a position that my device is disposed vertically, in order that an air vent may be provided, I provide the screw threaded member 8 with a cutaway portion 16 whereby when the screw threaded member 8 is partially unscrewed from the sleeve 6, the cutaway portion 16 flush with the reduced extension 11 will extend above the sleeve 6, thereby establishing communication between the interior of the barrel and the atmosphere, as will be obvious.

From the foregoing description and a study of the drawing it will be apparent that I have thus provided a novel and simple device whereby an air vent is provided for barrels whereby the passage of air may be permitted and which may be readily and easily locked open or shut.

It will be readily understood that I reserve the right to make various changes in the form, construction and arrangement of claim: I

A device of the character dGSCi'lbGCl comprlslng, a sleeve secured upon a barrel and v extending thereinto, said sleeve being internally screw threaded, a screw threaded member disposed in said sleeve, a head on'said member, a reduced portion formed onsaid screw threaded member, a second reduced portion extending from said first named re duced portion and forming therewith a shoulder, a washeron said second named retending from said first named reduced portion and terminating short of the head of said screw member. 7 7

In testimony whereof, I afiix my slgnature, in the presence of two wltnesses.

CLARENCE N. EASTER.
